This is an first step toward handling dependencies (so, a four-hour task
and an 12-hour task can take just two 8-hour days) but it also addresses
a display but that tasks that took a multiple of 8 hours showed up a day
too long in the Gantt.

With i18n there's no point in hard-coding labels for tagged resource display.
It's not sensible to reinvent the wheel too, so describe_tagged_resource
method for tickets just calls the corresponding module in Trac core,
and we'll get good localization/translations of labels for free.

This is the final part of bundled suggestions contributed by Itamar Ostricher.
Thank you for all the invaluable ground work and inspiration.

First, cleanup superfluous part of a REGEXP. But it turned out, that adding
the message while already rendering doesn't work, not even for wiki pages.
So I've changed the whole concept for message insertion.
